1o aid whom it may concern:

Be it known that I, WALTER Soon, a citi zen of the United States of America, and a resident of Plainfield, Union county, New 'Jersey, have invented certain new and useful Improvements in Delivery Mechanisms, of which the following is a specification.

The present invention relates generally to delivery mechanism for sheets of paper or other flexible material, and has more particular reference to sheet delivery mechanism used in printing presses.

In the class of printing machines known as two revolution, stop cylinder and similar machines, the printed sheets are generally delivered with the printed side up.

Sometimes, however, it is desirable to deliver the sheets with the printed side down. Furthermore, it is frequently desired to change from one style of delivery apparatus to another in the same machine, when doing different classes of work.

The object of my invention is to produce an improved structure of the character described, capable of delivering the sheets with the printed side down, and also to provide interchangeable means whereby sheets can be delivered either with the printed side up or down at will in the same machine.

In carrying out the above objects, my invention is characterized by two delivery boards located in different planes in combination with a reciprocating carriage for delivering the sheets with the printed side up to one of saidboards and a fly for delivering the sheets with the printed side down to the other of the said boards, together with driving means and connections fQlll both, disconnectible from either one at wi In the drawings I have embodied my. invention in a suitable form, but changes may of course be made without departing from the spirit of the invention.

In the said drawings: Figure 1 is a side elevation of a machine, embodying my invention. F igc 1 is a detail viewfof a removable washer for adjusting the level of the tapes over whiclTth'esheets pass. Fig. 2 is a view of part of Fig. 1 showing a modification. Fi 3 is an end view, partly -in section, of Fig.2: Fig. 4 is a detail view of the drop delivery. Fig. 5 is a diagramvniatic view showing the parts in position to deliver the sheet with the printed side down. Fig. (3 is a diagrammatic view showing the parts in position to deliver the sheet with the printed side up.

Similar characters of reference indicate corresponding parts in the different views.

1 indicates a framework suitably mounting the various parts of the machine.

2 is the impression cylinder. 7 is the fiat drop-delivery, for delivering sheets with thcprinted side up to the delivery board 8.

9 is a second delivery board constituting a receiving means for the sheets located in a plane different from and higher than the plane of the board 7 to which sheets are delivered with the printed side down by means of the fly 10. 1

Any suitable means may of course be employed for driving the fly-and drop delivery. In the present instance, the fly fingers 11 are mounted on a crank 11 on the shaft 12 carrying the pinion 13 operated by'means of therack 14- disconnectibly attached to the rocking lever 15 pivoted at 16 on the frame work and provided with a friction roll 17 engaging with the cam 18 mounted on the shaft 19 to which motion is imparted by means of the gear 20 meshing with the pinion 21 and through the train of gears t, 5 and 6 from the impression cylinder. It will be noticed that the fly fingersll by being mounted on the crank are so positioned as to be located at a point below the shaft 12, when the fly is in position to receive the sheets, and below the delivery board 9, thereby enabling the fly to deliver the sheets on a board in a plane diiferent from that of the drop delivery board.

The rack 14 is connected to the rocking lever 15 by means of two split bushings 22 so that it can be disconnected from thefsaid rocking lever, and is provided with af'f'stud 23 adapted to rest in the bracket 24611 the framework when the rack is disconnected from the rocking lever.

- The drop delivery consistsessentially of a reciprocating carriage 25 adapted to seize {and release the sheet at the proper periods operated by means of racks in a well known manner and by means of the pinion 26 with which engages the rack 27 disconnectibly attached to the-crank disk 28 by means of a split bushing 29 in the same manner as the rack of the fly and is also provided with a stud 30 adapted to rest in the bracket 31 of the framework when not in use.

In the present instance, the reciprocating carriage 25 is provided wlth the grippers 60 and 61 which are adapted to seize the sheet when the carriage is adjacent to the tapes 35 and 41 and to release the same when at Y the end of the stroke of the reciprocating known manner.

carriage in the opposite direction in a well The reciprocating carriage is further provided with the collapsible apron 62 for supporting the sheet. Mounted fast on the framework are the stationary racks (33 (only one of whch is seen) and with which engages the gears 64 on the carriage. Moving with these gears is the pinion 65 which engages with the sliding rack 66 operated by the gear 67 mounted on the same shaft as the pinion 26.

20 by means of the gear 32 mounted on the same shaft 33 as the crank disk.

Interposed between the two deliveries and the impression cylinder is a sheet path as 34, constituting a means for conveying sheets consisting of the lower tapes 35 traveling over the rollers 36 and 37 and driven from theigear 38 on the impression cylinder. The

of the latch 46 engaging with. the pin 47 of the frame 43.

In Figs. 2 and 3 T have shown a modification in which the crank disk 48 and cam 49 for operating respectively the drop delivery and fly are mounted on the same shaft 50 and adjustab e one with relation to the other by means of the slot 51 and set screw 52 in a well known manner. The two racks 53 and 54 are made disconnectible as previously.

When it is desired to deliver the sheets with the printed sidedown, the frame 43 carrying the upper ,tapes is swung upward and out of the way, as shown in the drawposition above the fly'fingers when position to receive the sheet by inserting the washer 40. The jrack 14 is connected to the rocking lever 15, andjthe rack the The crank disk 28 is driven from the gear andthe lower tapes areadjusted to adelivery disconnected from the crank drop and placed in the bracket 31; or if the disk,

' crank disk is mounted on a separate shaft,

the gear 32'can he slid sidewise upon the shaft 33 and out of mesh with the gear 20.

When it is desired to deliver the sheets with the printed side up, the rack 14 is disconnected from the rocking lever 15 and placed in'the bracket 24. The fly is swung up on the delivery board'9, the washer 4O removed from the sliding box of the lower tapes, and the as to properly guide the sheets into the drop delivery. The rack delivery is connected with the crank disk, or if the gear 32 has been brought out of mesh with the gear 20, it is moved back.

again into mesh.

By the foregoing means it will be seenthat I have devised an easily adjustable interchangeable means for delivering the sheets either with the printed side up or down.

Of course the same be used with either delivery by having it removable and by shifting it from one position to another. The claims should be construed accordingly.

What I claim is:

1; In a printing or other. machine, the combination with an impression or other cylinder, the sheets-with the printed side up, a delivery board for receiving the sheets from the said drop delivery, a delivery board located in a diflerent plane from that of the first board, a fly with the printed side down to the said second delivery board, a sheet path interposed between the two deliveries and the impression cylinder, drop delivery, either of-which is adapted to be rendered inoperative.

2. In a printing or other machine, the combination with an impression or other cylinder, of a drop delivery for delivering the sheets with the printed side up, a delivery board for receiving the. sheets from the said drop delivery, a delivery board located above the first delivery board,,a fly for delivering the sheets with the printed side down to the said second delivery board, a sheet path interposed between the two deliveries and the impression cylinder, and driving-means for the fly and drop delivery, either of which is adapted to berendered inoperative. 1 3.
